WASHINGTON (CNN) - Republican presidential hopeful Sam Brownback, dogged by low poll numbers and a poor fundraising showing last quarter, has decided to abandon his bid for the White House, people close to the senator tell the Associated Press.

Meanwhile, a campaign source tells CNN's Chief National Correspondent John King that all scheduling has been put on hold pending a "major announcement" from the Kansas Republican.

I am not a professional political advisor, but here's my suggestion. You are from Kansas, nobody knows you. Go back to the Senate, make a huge name for yourself. Try again in 2016 when Hillary leaves office.
